# 1.50c+20=33.50

## Enter Equation or Inequality

Solve the following equation
1.50c+20=33.50

Solve for c
1.50c + 20 = 33.50

## Group constants

Group our constants 20 and 33.50.
subtract 20 from both sides
1.50c + 20 - 20 = 33.50 - 20

1.50c = 13.5

## Divide each side of the equation by 1.50

 1.50c 1.50
 =
 13.5 1.5

c = 9

c = 9
